South Korea's Semiconductor Equipment Imports Surge 57% YoY, Boosting Performance Expectations for ASML and Others

Overview

This report tracks South Korea's semiconductor equipment import data, revealing a 57% YoY increase in April 2026, indicating strong demand in the country's semiconductor industry. Equipment suppliers such as ASML, Tokyo Electron, and Advantest are expected to benefit from this trend. Additionally, capital expenditures by South Korean memory manufacturers like Samsung and SK Hynix are highly correlated with import data, suggesting continued growth in equipment demand.

Core views

South Korea's semiconductor equipment imports grew 57% YoY in April 2026, showing significant momentum. Global imports rose 57%, while imports from Japan increased 29%, reaching a record high. This growth is primarily driven by expansion needs from South Korean memory manufacturers. ASML's system sales in South Korea are expected to reach EUR 2.1bn in Q2, down 26% QoQ but still doubling YoY. Tokyo Electron's imports in South Korea grew 62% YoY, reflecting strong performance in the market. Advantest's test equipment imports declined 21% QoQ but rose 49% YoY, with regression analysis suggesting Q1 sales could grow 70%. Furthermore, South Korea's equipment imports show strong correlation with capital expenditures from Samsung and SK Hynix, which are expected to increase significantly for the full year despite Q1 declines.

Analysis framework

This report employs a correlation analysis between import data and company performance, using regression models to forecast key equipment suppliers' results. First, trend analysis of South Korea's semiconductor equipment imports identifies key growth points and cyclical changes. Next, import data is matched with sales data from companies like ASML, Tokyo Electron, and Advantest in South Korea, using regression models to estimate sales expectations. Finally, capital expenditure trends from major South Korean semiconductor manufacturers (e.g., Samsung and SK Hynix) are incorporated to assess long-term equipment demand. This multidimensional data correlation analysis enables accurate performance forecasts for equipment suppliers.
